Just to add to the info, my understanding is that at least for the present
that refers to compiled code vs. compiled code, and the PowerPC assembler
client currently in use on the Mac is running faster. Once the 32-bit
bitslice code is final I'll look at it to see if an assembly version would
be both feasible and beneficial -- some things you can optimize, and some
things are only going to go so fast no matter what you do.
